Description:

JHA3901D SFP+-10GBASE-T Copper Small Form Pluggable (SFP) transceivers are based on the SFP Multi Source Agreement (MSA) . They are compatible with the 10Gbase-T / 5Gbase-T / 2.5Gbase-T / 1000base-T standards as specified in IEEE Std 802.3 . SFP+-10GBASE-T uses the SFP’s RX_LOS(must be pulled up on host) pin for link indication. If pull up or open SFP’s TX_DISABLE pin,  PHY IC be reset.

• SFP to Host Connector Pin Out

Notes:

1. Circuit ground is connected to chassis ground

2. PHY disabled on TDIS  > 2.0V or open, enabled on TDIS < 0.8V

3. Should be pulled up with 4.7k – 10k Ohms on host board to a voltage between 2.0 V and 3.6 V. MOD_DEF(0) pulls line low to indicate module is plugged in.  

4. LVTTL compatible with a maximum voltage of 2.5V.

• Cable Length

• +3.3V Volt Electrical Power Interface

The JHA3901G SFP+-10GBASE-T has an input voltage range of 3.3 V +/- 5%. The 4V maximum voltage is not allowed for continuous operation.

Caution: Power consumption and surge current are higher than the specified values in the SFP MSA

• Low-Speed Signals

MOD_DEF(1) (SCL) and MOD_DEF(2) (SDA), are open drain CMOS signals. Both MOD_ DEF(1) and MOD_DEF(2) must be pulled up to host_Vcc.

• High-Speed Electrical Interface

All high-speed signals are AC-coupled internally.

• General Specifications

Notes:

1. Clock tolerance is +/- 50 ppm

• Environmental Specifications

Automatic crossover detection is enabled.  External crossover cable is not required

• Serial Communication Protocol

All SFPs support the 2-wire serial communication protocol outlined in the SFP MSA. These SFPs use an MCU, can be accessed with address of A0h.

• EEPROM INFORMATION（A2）,optional

• Recommended Application Circuit

• Serial ID Memory Contents
